Study Notes
Nickel-Cadmium Secondary Cell
- Positive plates composed of nickel hydroxide (Ni(OH)â‚‚)
- Negative plates composed of cadmium hydroxide (Cd(OH)â‚‚)
- Electrolyte consists of distilled water and potassium hydroxide (KOH) with a relative density of 1.24 to 1.30
- Batteries have a relatively steady voltage during high-current discharge, making them suitable for engine starting
- Plates are constructed using a sintering process with active materials impregnated by chemical deposition
- This construction method allows for maximum active material usage in electrochemical reactions
- Plates are stamped to size and built into positive and negative plate groups, interleaved and connected to terminal posts, similar to lead-acid cells
